MEANS FOB. MAKING CASTELLATED NUTS.

Specification of Letters Patent.

Patented Sept. 2, 1919.

I 10 all whom it may concern.'

Be it known that I, FERNANDO OSCAR JaQU'ns, Jr., a citizen of the United States, residing at Providence, in the county of Providence and State oi' Rhode Island, have invented a new and useful Improvement in Means for Making Castellated Nuts, of which the Jfollowing is a specification.

In previous means of making castellated nuts the castellations are formed by cutting out portions oi the metal, usually by three or more distinct operations of a cutter across the nut or the metal is removed in some other Way.

The object of my invention is to improve the means of making castellated nuts, whereby the castellations are formed on the nut by pressure or compression, thereby eliminating the waste in metal heretofore lost in cutting out the metal in forming the eastellations.

Another object of my invention is to form the greater portion of the hole through the nut by pressure or compression, thereby saving the metal heretofore lost, in drilling out the hole in the nut.

Further objects of my invention are to improve the construction and reduce the cost of making castellated nuts.

My invention consists in the peculiar and novel construction and operation of means for making castellatcd nuts, as Will be more fully set forth hereinafter and claimed.

Figure 1 is an end View of the castellating member.

Fig. 2 is an end view of the nut holding member.

Fig. 3 is a side view of the castellating member and a sectional view of the nut holding member showing the members separated and a nut blank in the nut holding member in a position to be castellated.

Fig. 4 is a sectional view showing the members closed and the nut blank castellated.

Figs. 5 and 6 are top and side views respectively of the castellated nut.

In .the drawings 8 indicates a castellating member, 9 a nut holding member, 10 a nut blank and 11 a castellated nut.

The castellating member 8 has a hexagonal portion 12 the size of the nut to be castellated, each side 13 of which has at the end a projecting member 14 all shaped to form the eastellations on the nut. A round central hole forming stud 15 protrudes from the member 8 as shown in Fig. 3.

The nut holding member 9 has a hexagonal shaped cavity 16 the size of the nut to be castellatcd. The cavity 16, as shown in Figs. 3 and 4 has a Hat nut bottom 17 'in which is a round central bore 18 which eX- tends centrally through the member 9. A movable stud member 19 having the same size and shape as the stud l5, is movably supported in the bore 18 and extends into the cavity 16, the distance required, when the nut is being castellated. The stud member 19 has predetermined reciprocating movements operated by a cam, not shown, or other means. The nut 11 has the castellations 20. 20 and the usual Hat bottom 21 as shown, in Fig. 6.

When in use a nut blank 10 is placed in the cavity 16 with the stud member 19 protruding into the cavity, as shown in Fig. 3. The members 8 and 9 are new brought together under the required pressure thereby forming the castellations 20. 2O on the nut blank, as shown in Figs. 4 and 6 and the studs 15 and 19` simultaneously entering the blank forms the greater portion of the hole in the blank, leaving a thin transverse web 22, as shown in Fig. 4. The members 8 and 9 are now separated and the stud member 19 operated against the web 22 to push the castellated nut out of the cavity 16 where it is removed by an air blast or other means. In completing the nut the thin web 22 is punched out and the hole thus formed screwthreaded in the usual way.

As the uut blank now has just the right amount of metal to form the castellations and the greater portion of the hole in the nut, all of the metal heretofore Wasted in forming the castellations is saved and approximately nine-tenths of the metal heretofore lost in drilling the hole is also saved. and by condensing the metal by pressure a more perfect and durable castellated nut is produced and at less cost, than has heretotore been done.

It is evident that the same results are nbmined Whether the means for forming' the eestellations are on the member 8 or in the member 9.

Having thus described my invention I claim es new:

1. Means for making eestelleted nuts comprising two operating members having means for holding :t mit, ineens for vastellztling the nut my compre-seing the motel oi the mit, menne` for sinmlteneonsiy forming the greater portion of n hole in the mit by compression, and means for ejeetingl he eustellated nut from the operetin members.

2. Means for making eastellate nuts comprising a member having e cavity adapted to hold a nut and a member adapted to enter said cavity and having means for forming eastelletions on the nut by compressing the metal of the nut.

3. Means for making cnstelleted nuts comprising a member having a; cavity the shape und size of the nut to be castellated und :i member having a, portion the sha e und size of the nut to be eestellated, said member lmving :i sliding fitin seid e'ftvity and menne4 for formin r enstelletions on the mit by compressing the metal of the mit.

14. Moens for making eestell'ftted mits comprising :i member lmving :i envity the shape und size oi' the nut to be ('nsllellzlted :and e cent1-nl bore, n movable stud member in the bore :md extending into the cavity, at member having e eentrnl stud, projecting parte adopted to form custellations on e mit and :t slidii'ig fit in the cavity in the first member, wherebv eastellations are formed on, and the greater portion of a hole is formed in a nut, by compressing the metal of the nut. i

In testimony whereof, I have signed my name to this specification.
